If you play the Star Wars music yourself and then us it in a video, it will still get a copyright strike if you monetize the video. It's not just the recording that's covered by the copyright, it's the arrangement of the music. Until the 2047 or so, any recording of the Star Wars music will get a strike.

You still can't do that and use it in your video, legally.  What backyardlegos is saying is correct, maybe rephrasing it will make more sense.
Not only are the actual recordings played by the London Symphony Orchestra and conducted by John Williams copyrighted, the arrangement itself is.  Long before the recording was copyrighted the music itself, that arrangement of notes, any theme from any Star Wars film is under copyright, whether you play the notes yourself on a keyboard or use the original recordings, you can't do it.
You'll need to either write your own music entirely (if you can get it to be reminiscent of Star Wars without using any of their themes that would be awesome, but takes a certain talent) or use royalty free music off the internet.  Maybe you could try getting a composer from here to work with you, it all depends on a lot though.

I hope this makes more sense. 
TLDR: Basically, no; you still can't do that.
